STOVE.

SPECIFICATION forming part of Leners Patent No. 706,589, dated August12, 1902. Application iiled September 4, 1901. Serial No. 74,300. (Nomodel.)

To a/ZZ whom it may concern:

Be it knownthat 1,-W1LLIAM NULL,a citi`4 zen of the United States,residing at Philoah, in the county of Putnam and State of Ves'tVirginiaphave invent-ed aV new and Vuseful Stove, of which the followingis a specification.

' This invention'relates to stoves, and is particularly designed toprovide an improved cooking-stove, wherein the re-boX is located so asto effectually heat both the cooking-oven and the warming-oven and alsodisposed so as to form a convenient support for a watertank, and therebyto leave the top of the stove unobstructed for cooking vessels and thelike. It is furthermore designed to employ a single damper forcontrolling the supply of heat for the two ovens and to have said damperl0- cated in position for convenient adjustment.

Another object is to provide for convert iently supplying fuel to thefire-box without removing the watertank therefrom and'also to providean, improved grate-and ash-pan arrangementwherebythe grate may beconveniently removed whenever desired and is normally held againstdisplacement by the ash-pan. s

With these and other objectsin view the present invention consists inthe combination and arrangement of parts, as willbe hereinafter morefully described, Ishown in theaccompanying drawings,and particularlypointed out in the appended claims, it being understood that changes inthe form, proportion, size, and minor details may be made within thescope of the claims without departing from the spirit or sacrificing anyof the advantages of the invention.

In the drawings, Figure l is a perspective View of a stove constructedand arranged in accordance with the present invention.` Fig. 2 is alongitudinal `sectional view thereof. Fig. 3 is a detail sectional viewtaken longitndinally'through the fire-box. Fig. 4 is an enlarged detailsectional view taken transversely through the front of the fire-box.Fig. 5 is an enlarged detail sectional view taken through thedamper-operating mechanism. Fig. 6 is a detail elevation of the meansfor 5o locking the damper.

Like characters of referencedesignate corv responding partsin all thefigures of the drawings.'

In carrying out the present invention there is provided a substantiallyrectangular stove- 4body 1, whichhas anupper cooking-oven 2 and a lowerwarming-oven 3, said ovens being separated by a. space or 'lue formedbetween the bottom and top of 'the ovens, there being a plurality oflongitudinal ribs 4:' located within said space or flue to stiften andstrengthen the bottom and top plates. The warming-oven extends from theback to the front of the stove, while the cooking-oven is terminatedshort of said front and rear ends by means of the front and rear plates5 and 6, respectively, and the top of the oven is formed by means ofatop plate 7, located slightly below` the top of the stovetop,whereby aue or V`heat-passageis provided that extends entirely around thecookingbven and also between the two ovens. The cooking-oven is providedwith the I opposite hinged doors 9 and also with a removable rack10,'tl1`at may be held on either of t'ne corresponding pair of flanges10,formed Yin the front and rear Walls of the oven. rlhe .warming-ovenisalso provided with doors 11,

one of-which has a plurality of draft-open ings which` arefcontrolled bymeans of a damper-slide 1.2, mounted upon the inner side of the door andhaving a handle 13 pro- `jeetedoutwardly through a longitudinal slotformed in the door.

The fire-box 11iE is supported upon a front extension of the bottom orbase ot' the stove and has its top 15 located substantially in line withthe bottom of the cooking-oven, and

-is"also provided with the usual stove-holes. It will herebe noted thatthe nre-box is projected in front of the stove and forms a support orseat for a water-tank 16, whereby the top of the stove is unobstructedand the 'water-tank receivesthe full benefltof` the fire. A suitablehinged shelf 17 is provided at one end of the top of the fire-box, sothat the water-tank maybe moved outwardlyand partly supported by thisshelf should it be desired to expose a greater portion of the top of thefire-box. Ordinarily the watertank will be somewhat shorter than therebox in order that a portion of the top thereof Inay always be exposedfor the support of` IOC ' mally closed by a suitable door 21.V

' rest upon the bottom of the fire-box.

such cooking utensils as may require an intense heat. f

Within the fire-.box there is provided a grate which consists of aslotted bottom 18, having opposite outwardly-directed longitudinaliianges or ribs 19, that are slidably received within correspondinggrooves 20, formed in the front and back of the lire-box, the gratebeing insertible through a doorway provided at one end of the lire-boxand nor- The bottom of the grate is also provided at its four cornerswith supporting-feet 22, which The grate also has-the front and rearlongitudinal walls or sides 23 and 24, respectively, of which the frontside is provided with a pluralityof openings 25, which register withcorresponding openings 26, formed in the front of the fire-box, so as tosupply air to the fire. The opposite ends of the grate are open and arenormally closed by means of the opposite ends of the fire-box. The gratemaybe readily shaken by opening the door 21 and applying a hooked pokerthrough the adjacent slat in the bottom of the grate, and is alsodesigned to remove-the grate in an endwise direction through the door.

In orderthat fuel may be supplied to the grate without removing thewater-tank from the top of the lire-box, an opening 27is formed in thefront of the lire-box and is closed by means of a door 29, which islocated upon the outer side of the fire-box and hinged at its loweredge, there being a suitable latch or fastening 30, located at the upperedge of the door, so as to normally lock the latter. At opposite sidesof the fuel-opening there is provided the upright plates 31, which aresuitably secured or formed integrally with the front of the fire-box andhaving their outer edges inclined upwardly and outwardly and providedwith inwardly-di rected longitudinal ribs or flanges 32. The door 29fits between these plates and is limited in its outward movement bymeans of the flanges 32, so that when the door is opened it cooperateswith the opposite plates 3l to form a chute or hopper for convenience inintroducing the fuel to the fire-box. 1

Beneath the grate there is located an ashpan 33, which has its outer endprojected through an opening 34, formed in the front of the fire-box,the outer edge of the pan being provided with a plurality of notches orrecesses 35, which communicate with the interior of the pan. The notchedfrontedge of the ash-pan is normally projected beyond the front of thelire-box, and upon this edge there is mounted an endwise-slidabledamper-plate 36, which is provided at its inner edge with a plurality ofnotches 37 to register with the notches in the pan to provide passagesfor conveying air into the lire-box and beneath the grate. When theash-pan is in place, it iits snugly between the legs of the grate, and

damper to an intermediate position between the horizontal and uprightfines the products of combustion may pass entirely around thecooking-oven, and by adjusting the damper to close the upright flue allof the heat and products of combustion may be directed .between the twoovens, so as to apply more heat to the warming-oven, land by closing thevhorizontal i'lue all of the heat and products of combustion will passupwardly and over the top of the cooking-oven and iinally out throughthe smoke-pipe of the stove without having any eiect upon thewarming-oven.

To provide for the convenient adjustment of the damper, one of thejournals thereof is projected beyond one side of the stove, as indicatedat 39, and upon this projected journal portion a slidable sleeve 40 ismounted, said sleeve being provided at its outer end with a crank-handle41 and at its inner end with a lateral ratchet finger or projection 42for cooperation with an arcuate rack 43, applied to the adjacent side ofthe stove. Within the sleeve Athere is provided a suitable spring 44,which bears in opposite directions against the sleeve and the journal,so as to yieldably hold the sleeve at its inward limit with the fingeror projection 42 in yieldable engagement with the rack, so that bymanipulation of the crank-handle the damper may be readily adjusted andthe ratchet-finger will work over the rack and finally lock the damperat the completion of the adjustment thereof; also, the damper maythereby be held at a plurality of adjustable positions, so as to varythe size of the opening between the fire-box and the two lines.

What I claim is- 1. In a cooking-stove, the combination of a lowerheating-oven, a cooking-oven located above the same and havinga fluesurrounding the top, bottom and opposite ends of the cooking-oven, thetop of the heating-oven and the bottom of the cooking-oven forming thewalls of the flue portion between the two ovens, and the bottom of thelower oven being formed by the bottom of the stove, a tire-box projectedin front of the heating-oven and having its top located below the maintop of the stove and above the top of the lower oven to form a seat orsupport for a water-tank, the back of the fire-box being terminatedsubstantially at the top of the lower oven, whereby a directcommunication is had between the hre-box and IOO IIO

the flue or space between the two ovens, and a vertically-swingingdamper pivoted substantially at the intersection of the inner edges ofthe front and bottom flue portions and capable of swinging verticallytoward the ire-box to open and close the lower end of the vertical flueand the front end of the horizontal fine, whereby either of these finesmay be Wholly closed.

2. In a stove, the combination with a rebox, of an endwise-removablegrate having legs, and an ash pan inserted through an opening in thefront of the fire-box and lying snugly between the legs to preventaccidental displacement of the grate.

3. In a stove, the combination with a firebox having draft-openingsformed in the front thereof, and a door at one end, of a grateinsertible through the door and having draftopenings corresponding tothe similar openings in the fire-box, and an ash-pan removably insertedthrough an opening in the front of the fire-box and having its outer endnormallyprojected externally of the lire-box, and a slidable dampermounted upon the projected portion of the ash-pan.

In testimony that I claim the foregoing as my own I have hereto afxed mysignature in the presence Vof two witnesses.

WILLIAM I-I. NULL.
